New Changes in American Waste Paper Standards

With the continuous improvement of the American waste paper recycling system, there are new changes in waste paper standards. The new standard was developed by the “Recycling Industry Association of the United States” and is called Waste Specification Circular 1998 (abbreviated as SSC-98). This standard is a guiding standard and is not mandatory. The entire standard classifies and regulates non-metal and metal wastes.

The standard PS-96 is compared below for your reference.

No. 3 waste paper is currently widely used in domestic production processes such as whiteboard paper and high-strength corrugated paper. The annual import volume reaches 100,000 tons. SSC-98 removed No. 3 "Special waste magazine" from use, and changed it to No. 2 "Waste magazine". The standard is unchanged. It is still defined as follows: "It consists of a mixture of waste papers of various qualities that have been picked up and packaged and supplied. The content of groundwood pulp does not exceed 10%, debris does not exceed 0.5%, and the total amount of non-similar paper does not exceed 3%." At the same time, the No. 1 "waste of paper" in PS-96 was renamed No. 1 "soft waste magazine", and the standard remained unchanged.

The P-96 standard refers to No. 7 as a "special old newspaper." The standard stipulates that "freshness is not affected"; and non-similar papers are allowed to reach 2%. The SSC-98 renamed No. 7 as “de-inking-grade old newspapers”, apparently in order to adapt to the current situation of large-scale papermaking equipment. Imagine that even No. 8 “Old newspapers with special deinking papers” can have a non-bleachable grade. Can No. 7 be used as a deinking device in domestic small papermaking equipment? The SSC-98 also removes the “freedom from dampness” in the No. 7 standard. As a result, claims due to dampness will lose their textual basis. In addition, SSC-98 reduced the proportion of non-identical papers to 0.25% while clarifying “allowing publications to be included”.

PS-94 has stricter requirements for the No. 8 "October Corrugated Paper Container" (OCC), and the PS-96 has lowered the standard, causing the original No. 11 factory to produce kraft linerboard to complain about the decline in quality. Some of the factories then changed to No. 12 “Selected Old Corrugated Carton Boxes”, which is considered to be similar to PS-94 Era 11 and is slightly better. Now SSC-98 has further raised the standard on No.12 “Selected Old Corrugated Boxes”, reducing the content of non-similar papers from the original 5% to 2%. It can be said that if the supply can be strictly implemented according to the new standard, the containerboard manufacturer should be able to use it with confidence. In addition, illegal traders once used the No. 12 carton to chop and faked No. 13 “double-cut double-sided corrugated corrugated new trim” on the market. The price was lower than the actual No. 13 and far higher than No. 12. Life manufacturers must be careful to identify.

Bonsai Pot

Like the purple sand pot, the bonsai pot is made of a kind of high-quality pottery clay that is a specialty of Yixing (hidden deep under the rock and mixed in the mud, so it is called "rock in the rock" or "mud in mud". The texture is delicate and flexible. Strong plasticity), after being selected, refined and refined, it is fired at a high temperature of 1000-1250 degrees. It has no glaze on the inside and outside, and has fine texture, toughness, good physical properties, and drainage and air permeability are very suitable for the growth of trees and flowers. Its color is ancient and quiet, its shape is generous and diverse and complements the potted flowers and trees. It is simple, rich and rich in ethnic characteristics. In addition, it is meticulous and exquisite. It can be said that it has both artistic value and practical value, which is unmatched by other types of pots.
The beauty of the large bonsai pots lies in its unique decorative means. Skilled craftsmen of the past dynasties, through their own exquisite skills, integrated the pot color, shape, style recognition, inscription, calligraphy and sculpture, etc., so that the purple sand flowerpots can be beautiful in the simplicity and give people a visual enjoyment.
The colors of the small bonsai pots are colorful. Among them, the three colors of vermilion, purple and beige are the main colors; during the firing process, as the temperature after entering the kiln is different, the depth and intensity of the color changes more and more; coupled with the accumulation of long-term practical experience of the artists, they use different proportions of mud With the preparation of materials, there are dozens of colors after firing. For example, the colors are named iron blue, sky blue, maroon, begonia red, cinnabar purple, water green, agarwood, sunflower yellow, cold golden color, pear skin, blue gray, dark green, patina, brown black, durian skin and other colors. If you observe carefully, there is a little bit of white sand in the mud, with silver light flashing, and some of the mud is mixed with coarse mud sand or steel sand, and the particles are looming and extremely eye-catching. Although the color changes in the purple sand are many, the tones are very calm. If you plant ancient piles of pine and cypress, it will be more simple and simple.
The shapes of the clay bonsai pots range from very deep thousand-tube basins to very shallow basins, from round basins with a diameter of about one meter to finger-sized miniature basins. There are all kinds of specifications, various forms of basin mouth, basin surface, basin hole The changes in the feet of the basin are even more varied, which is even better than the shape of the purple clay pot. It can be described as a masterpiece of the shape of the vessel.
